Use when working with .base files, creating database-like views of notes, or when the user mentions Bases, table views, card views, filters, or formulas in Obsidian.\n---\n\n# Obsidian Bases\n\nThis skill enables Claude Code to create and edit valid Obsidian Bases (`.base` files) including views, filters, formulas, and all related configurations.\n\n## Overview\n\nObsidian Bases are YAML-based files that define dynamic views of notes in an Obsidian vault. A Base file can contain multiple views, global filters, formulas, property configurations, and custom summaries.\n\n## When to Use This Skill\n\n- Creating database-like views of notes in Obsidian\n- Building task trackers, reading lists, or project dashboards\n- Filtering and organizing notes by properties or tags\n- Creating calculated\u002Fformula fields\n- Setting up table, card, list, or map views\n- Working with .base files in an Obsidian vault\n\n## File Format\n\nBase files use the `.base` extension and contain valid YAML. They can also be embedded in Markdown code blocks.\n\n## Complete Schema\n\n```yaml\n# Global filters apply to ALL views in the base\nfilters:\n  # Can be a single filter string\n  # OR a recursive filter object with and\u002For\u002Fnot\n  and: []\n  or: []\n  not: []\n\n# Define formula properties that can be used across all views\nformulas:\n  formula_name: 'expression'\n\n# Configure display names and settings for properties\nproperties:\n  property_name:\n    displayName: \"Display Name\"\n  formula.formula_name:\n    displayName: \"Formula Display Name\"\n  file.ext:\n    displayName: \"Extension\"\n\n# Define custom summary formulas\nsummaries:\n  custom_summary_name: 'values.mean().round(3)'\n\n# Define one or more views\nviews:\n  - type: table | cards | list | map\n    name: \"View Name\"\n    limit: 10                    # Optional: limit results\n    groupBy:                     # Optional: group results\n      property: property_name\n      direction: ASC | DESC\n    filters:                     # View-specific filters\n      and: []\n    order:                       # Properties to display in order\n      - file.name\n      - property_name\n      - formula.formula_name\n    summaries:                   # Map properties to summary formulas\n      property_name: Average\n```\n\n## Filter Syntax\n\nFilters narrow down results.
